Percutaneous Nephrolithotomy

Patients with large kidney stones or staghorn calculi may benefit from a surgical procedure called a percutaneous nephrolithotomy (PCNL). This procedure is done under a general anesthetic and involves a small incision in the back where a tube can be inserted into a kidney. A special telescope called a nephroscope is inserted to locate the stones. Through the nephroscope, various instruments can be inserted to break up and remove stones.

This procedure generally involves admission to hospital for two to three days. After surgery, a catheter remains in the bladder over-night, and a nephrostomy tube remains through the small incision in the back. The nephrostomy tube is usually removed prior to the patient’s release from hospital.

The procedure is highly effective for eliminating large stones.
